I used a lot of MF-lenses (Olympus OM, Voigtlaender, Canon RF) with my Pan GF1. But I am missing some control, It should be possible to give some focus-information when manual focussing. Lets say, you have selected a "spot, f.i.in the middle, and an indication (red or green) My idea is that wenn focussing, you also change the contrast in that spot. The changing could be showed with green (sharper) or red (unsharper). Or may be more sophisticated. The solution now, with 10x zooming on a spot is fine but a bit difficult to use out of hand!
